Question

**Part A**

A sample of ideal gas at room temperature occupies a volume of
27.0 L at a pressure of 202 torr . If the pressure changes to 1010
torr , with no change in the temperature or moles of gas, what is
the new volume, *V*2?

Express your answer with the appropriate units.

**Part B**

If the volume of the original sample in Part A (*P*1 =
202 torr , *V*1 = 27.0 L ) changes to 60.0 L , without a
change in the temperature or moles of gas molecules, what is the
new pressure, *P*2?

Express your answer with the appropriate units.

For a certain amount of gas at constant temperature, the
pressure and volume have an inverse relationship (Figure 1) . This
is called *Boyle's law*:

*P*1*V*1=*P*2*V*2

All pressure–volume–temperature relationships for gases can be
combined into a single relationship known as the combined gas
law. This expression can be used when looking at the effect of
changes in two of these variables on the third as long as the
amount of gas (number of moles) remains constant. To use the
combined gas law properly, you must always express the temperatures
in kelvins. The combined gas law can be represented as follows:
P1V1/T1=P2V2/T2
